如何使用 PHP 和密码运行 Bash 脚本

Question

How can I protect a bash script (Ubuntu) with a password and the call it with PHP?

If I simply use ALL=(ALL) NOPASSWD:/var/www/my_bash_script.sh this will allow to PHP to call the script from anywhere anytime without password, that's not what I want.

PHP has a number of options to do this.

With the very little information given, this sample is just a guess using the shell_exec option.

<?php
header('content-type: text/plain');
echo shell_exec('/var/www/my_bash_script.sh yourPassWord');

The file permissions of the my_bash_script.sh file are important.

They need to be suitable for execution by the same user or group that the webserver (effectively the php process that executes the php script and therefore the bash script) uses.
